In order to solve the problems that the air conditioning equipment in the prior art does not have an oxygen detection function and cannot be adjusted in time when the indoor oxygen content is low, the air conditioning equipment is designed and provided. As shown in fig. 1 and 2, the air conditioning apparatus 1 includes a casing 10. The shell 10 is provided with a return air pipe section 11 and an outlet air pipe section 12. Wherein the return air pipe section 11 is provided with at least one return air inlet 17, and the outlet air pipe section 12 is provided with at least one air outlet 13. The air return opening 17 and the air outlet 13 are respectively communicated with an air-conditioning room. The casing 10 is further provided with at least one fresh air inlet 15. The fresh air opening 15 communicates with the outdoor space to introduce air outside the air-conditioned room into the air-conditioning apparatus. At least one oxygen sensor 18 is disposed in the return air duct section 11. An oxygen production line section 14 is also provided in the air-conditioning apparatus 1. An oxygen generation module 16 is disposed in the oxygen generation tube section 14. The oxygen production pipe section 14 is communicated with the air outlet pipe section 12. The air conditioning device is also provided with a control chip (not shown in the figure). An oxygen sensor 18 is provided in the return air duct section 11 for sensing the oxygen concentration of the return air in the return air duct section 11, i.e., the oxygen concentration in the conditioned room. When the oxygen concentration in the air-conditioned room is lower than the normal volume content, the oxygen sensor 18 generates and outputs an oxygen concentration detection signal. The oxygen sensor 18 is connected with one input end of the control chip, and the output end of the control chip is connected with the oxygen generation module 16. Control chip receives the oxygen concentration detection signal that oxygen sensor 18 generated, generates and output drive signal to system oxygen module 16, and system oxygen module 16 begins work, and the air that flows in from new wind gap 15 passes through system oxygen pipeline section 14 and air-out pipeline section 12 in proper order and sends into the air conditioning room from air outlet 13 in, and system oxygen module 16 promotes the oxygen content in whole casing 10, and the oxygen content of the air that sends into the air conditioning room from air outlet 13 promotes. The oxygen sensor 18 keeps the detection state, when the oxygen concentration in the air-conditioning room is higher than the normal volume content, the oxygen sensor 18 stops outputting the oxygen concentration detection signal, the control chip does not generate and outputs the driving signal to the oxygen generation module 16, the oxygen generation module 16 stops working immediately, and the oxygen concentration in the air-conditioning room is prevented from being too high. In the air conditioning apparatus provided in this embodiment, the control chip may be an independent single chip, may also be implemented by a PLC, and may also be another integrated circuit having an independent input/output port. The sensing probe of the oxygen sensor 18 may be a porous ZrO2 ceramic tube, and porous platinum (Pt) electrodes are respectively sintered on two side surfaces of the ceramic tube. When the oxygen concentration is higher, the oxygen ion concentration difference between the inner side and the outer side of the ceramic tube is small, and the generated electromotive force is very low; when the oxygen concentration is low, the oxygen ions on the outer side of the ceramic tube are less, the formed electromotive force is high, and a detectable oxygen concentration detection signal is generated. Sensor output signal's analog-to-digital conversion circuit can choose the circuit of recommending among the circuit or the control chip technical manual that disclose among the prior art for use, not the utility model discloses a protection is key, no longer gives unnecessary details here. In this way, when the oxygen concentration in the air-conditioning room is low, the air flowing in from the fresh air port 15 flows through the oxygen generation pipe section 14, the oxygen concentration is improved through the work of the oxygen generation module 16, and the air with high oxygen concentration is timely supplemented into the air-conditioning room; when the oxygen concentration in the air-conditioned room is higher, the oxygen generation module 16 stops working automatically, so that the constant oxygen state in the air-conditioned room is realized, and the use comfort of a user is improved.
The oxygen generation module 16 is preferably a molecular sieve oxygen generation plant. The oxygen is decomposed by utilizing molecular sieve physical adsorption and desorption technology.

The molecular sieve discharges the adsorbed nitrogen back into the ambient air during pressure reduction to form recycle. The waste gas with higher nitrogen content can be guided by a small fan and discharged from the fresh air port 15 reversely. The fresh air opening 15 can be selectively arranged above the oxygen production pipe section 14 or above the air outlet pipe section 12. As shown in fig. 2, when the fresh air inlet 15 is opened on the air outlet pipe section 12, after the oxygen generation module 16 starts to work, more fresh air (as shown by an arrow F in fig. 2) is mixed with air (as shown by an arrow O in fig. 2) with higher oxygen content in the housing 10 and return air (as shown by an arrow R in fig. 2), and further introduced into the air-conditioned room through the air outlet 13, the oxygen concentration in the air-conditioned room slowly rises, such a structure is more suitable for laboratories, plants and other areas, and avoids the rapid rise of the oxygen concentration from causing an obvious concentration gradient in the room, thereby accelerating combustion or chemical reaction. As shown in fig. 3, when the fresh air is provided on the oxygen generation pipe section 14, after the oxygen generation module 16 starts to work, more air (shown by an arrow O in fig. 3) with higher oxygen content and return air (shown by an arrow R in fig. 3) are mixed, and further introduced into the air-conditioned room through the air outlet 13, so that the oxygen concentration in the air-conditioned room rises rapidly. As a more preferable mode, it is preferable that a first flow control valve 21 is provided at the outlet 13 and a second flow control valve 22 is provided at the fresh air port 15. The flow rate of the mixed air is adjusted by adjusting the valve opening degree of the first flow control valve 21 and the second flow control valve 22, and the flow rate of the outlet air flow is further adjusted.
Referring to fig. 1, the housing 10 is of a generally rectangular design. The return air duct section 11 and the outlet air duct section 12 are preferably designed at both ends of the casing 10, and the outlet 13 and the return air inlet 17 are formed at both end surfaces of the casing 10. The air outlet 13 and the air return opening 17 can be communicated with an air conditioning room, and can also be communicated with the air conditioning room through connecting parts such as corrugated pipes, pre-buried pipes and the like. The oxygen production pipe section 14 is preferably arranged between the return air pipe section 11 and the outlet air pipe section 12. The return air pipe section 11, the outlet air pipe section 12 and the oxygen making pipe section 14 can be integrally formed, but in a more preferable mode, the oxygen making pipe sections 14 of the return air pipe section 11 and the outlet air pipe section 12 are designed to be independent from each other, and can be assembled and clamped with each other to form the whole shell 10. In this way, the technician can adjust the relative positions of the three pipe sections according to the actual environment and, if necessary, add other functional pipe sections to them under different installation conditions. For example, in this embodiment, it is further preferable to add an air cooling pipe section 19 between the return air pipe section 11 and the oxygen production pipe section 14, and at least one heat exchange device (not shown in the figure), such as a water-cooled heat exchanger or a heat exchange core, is disposed in the air cooling pipe section 19 to perform temperature and humidity processing on the indoor return air, so that the air conditioning device has more various functions and meets the use requirements of different users. The fresh air opening 15 is preferably opened on the upper end surface 23 of the shell 10, and an induced draft plate 20 is arranged at the fresh air opening 15. In order to improve the fresh air quality, it is preferable that a filter assembly 24 is further provided at the fresh air port 15. The filter assembly 24 includes at least one coarse screen.
